During the period from January, 1948, to June, 1953, study was made of 454 culturally proved cases of tinea capitis in the dermatology clinic at Indianapolis General Hospital. For the purpose of record, these cases have been reviewed and tabulated. To our knowledge this is the only review of tinea capitis issuing from Indiana in recent years.
The accompanying table demonstrates the relative frequency of the causative organisms. Positive cultures were a prerequisite for inclusion in this Table.
The percentages in this Table are typical of the urban population of clinic class of patients. According to communication with the staff physicians, the cases seen in private practice have shown roughly 51% caused by Microsporum audouini, 25% by M. lanosum, 10% by M. gypseum, and 14% by T. gypseum in central Indiana.
N. F. Conant confirmed three of the cultures of Trichophyton tonsurans.
